following is a specification, reference being had therein to theaccompanying "drawing:

According to the former practice of forming and wrapping round bales ofcotton, a' section of the burlap or other cover fabric is fed into thepress after the bale has been completed; and after the cover fabric hasbeen completely wrapped around the bale the press is stopped andpreliminary fastening means such as steel pins are manually insertedthrough the overlapped parts of the cover to temporarily secure it inplace. Then the press is opened and the bale ejected after which .thecover can be permanently sewed and the temporary fastening meansremoved. The ordinary method as described makes it necessary to stop thepress after the completion of each bale, this resulting in considerableloss of time.

The object of this invention is to provide a method whereby the covercan be put in place and temporarily fastened while vthe press is inmotion. p

The drawings illustrate some of the various devices by which" myimproved method of forming and fastening round bales can be carried on;and therein:

Figure 1 represents diagrammatically a round bale press and a section ofcover being wrapped around a bale in accordance with my improved method;Figs. 2, 3 and 4 are plan side and end views respectively of thepreferred form of fastening device,

this being the form illustrated in Fig. 1;

Fig. 5 is a plan view of a bale showing the temporary fastening devicesin place; Fig. 6 is a view similar to Fig. 5 showing the iastenilggdevices diflerently arranged; Figs.

8 an spectively of a modified form of fastening device; Fig. 10 is aperspective view showing another modified form of fastemng device. Fig.11 is a perspective view of a bale showing in place fastening devices ofthe sort shown in Fig. 10. Fig 12 1s a conventional illustration showingin section Specification of Letters Patent.

Referring to the drawings, A represents as a whole a round bale presswhich, so far as my invention is concerned, can be of any one of avariety of sorts. For the purpose of illustration, however, I have showna press in which there are a plurality of rolls, 1, 2 3, 4, 5, 6, 7 and8 mounted to inclose a cyllndrical bale forming space. The rolls aremounted on a suitable framework one section of which, carrying the rolls6, 7 and 8, is movable to permit the ejection of the finished bale. Therolls can be driven by any suitable mechanism and the driving mechan smis not shown in the drawing as 1t constltutes no part of my presentinvention. The cotton bat is fed in preferably Patented Aug. 8, 1916.Application filed July 7, 1915. Serial No. 88,578. i

between the rolls 1 and 8 and forms the w cylindrical bale which isindicated at B. Agfter the bale has reached the required denslty thefeeding of the bat is temporarily stopped and a strip of burlap or othersuitable cover fabric is fed into the press to wrap around the bale. InFig. 1, for the purpose of illustration, I have shown the cover 9 asbeing fed in between the rolls 1 and 8, but it will be understood thatthe exact point of feeding is immaterial. To the cover fabric at thepart which will overlap another part after the bale is wrapped, I secureone or more fastening devices 10. Each device 10 has pointed projections11, 11 which penetrate the fabric and lie in such position that theywill be ready to penetrate the overlapped fabric when they reach thebale. The result is that as the fabric carrying the fastening devices 10is completely wrapped around the bale the pressure of the rolls forcesthe projections 11, 11 into the inner layer of the cover fabric, thustemporarily fastening together the two fabric parts. Preferably thecover fabric is fed from a roll such as that indicated at 12. When suchroll is used the operator with a knife osevers the fabric along a linejust back of the fastening devices 10, just before the fastening devicesenter the press. If preferred, however, the fabric can be out in advanceinto sections of the proper length and the sections fed singly into thepress. I

As soon as the section of cover fabric with its fastening devices hasbeen fed into the press the temporary fastening takes place and the balecan be at once ejected without stopping the press. As soon as the baleis ejected the press is again closed and the formation of a new bale isstarted. The ejected bales with the temporary fastening devices. can bethen made ready for shipment by securing the covers more permanently bysewing or otherwise, the temporarv fastening means being removed.

In Figs. 2, 3 and 4 I have shown in detail one form of fastening devicewhich is found suitable. It comprises a body part 13 which By preferencethese projections are provided with barbs 15, 15 which prevent the readyremoval of the fastening device from the fabric after the projectionshave once pierced it. I

When fastening devices of the sort shown in Figs. 2 to 4 are used theyare preferably arranged in the manner indicated in Fig. 5, that is, twoof them are provided, and each is pointed inward toward the center ofthe strip of cover material. The cover material is repeatedly pierced inorder to hold the device in place and the pointed projections 11, 11 areeither forced through the fabric or are in position ready to be forcedthrough as soon as the pressure of the press is applied. While thearrangement shown in Fig. 5 is preferable it is not the only one thatcan be used.

In Fig. 6 I have shown the fastening devices arranged in another way,simply to' show that my invention is not limited to any particulararrangement.

In Figs. 7, 8 and 9 I have shown another form of fastening device inwhich the body part 13 is provided at each end with pointed projections11, 11, these having barbs 15, 15 The fastening device shown in Figs. 7to 9 is adapted to be fastened to the cover fabric by having the pointedprojections 11 11 tening device shown in Fig. 10 is intendedto serve notonly as a preliminary fastening device but also as a permanentfastening. Flg. 11 shows a bale having a cover fastened insertedtherethrough. Otherwise the device is used in the same in place bydevices of this sort shown in Fig. 10. When this device is to be usedthe cover fabric is cut into sections of the proper length and severalof the fastening devlces are secured at one end edge, the fabric atthisedge being doubled back as indicated by dotted line in Fig. 11. One setof the pointed projections 11", 11 are forced through the doubled fabricand the other set is left free to ierce the overlapped part of thefabric as t e fabric is wrapped around the bale.

One of the most important'advantages of my improved method and device isthe saving of time between the completion of-one bale and the startingof the next. According to the earlier practice, forty seconds and upwardwere required to feed in the cover fabric, to stop the press andmanually insert the temporary fastening pins, to eject the bale, and toclosethe ress to make it ready for the next bale. y using my improvedmethod it is possible to reduce this time to about twenty seconds, thatis, to about one-half of the time formerly required. This saving of timeis of especial importance when but a single press is used for eachbat-former and a bat accumulator provided for taking the bat while thecompleted bale is being wrapped and ejected. It is desirable to cut downas far as'pos sible the time during which the accumulator is used and,as above stated, by making use of my invention this time can be reducedapproximately one-half.

Another important advantage incident to my invention is that the coverfabric is fed to the bale under tension and that thetemporary fasteningdevices are forced into place while the tension in the fabric ismaintained. When the temporary fastening pins were inserted manually itwas customary for the operator to loosen up the fabric somewhat in orderto facilitate the insertion of the pins. This loosening of the fabricobviously permitted a corresponding expansion of the bale after itsremoval from the press. According to my invention. the fabric is keptunder tension throughout and there is little or no opportunity for thebale to expand.

While I have above described more or less in detail each of the deviceswhich can be utilized for carrying out my method, I do not hereinpresent claims for these, having presented claims therefor in anotherappl1-' cation No. 843,007, filed June 4, 1914, and herein claiming themethod of wrapping and fastening the wrap ers for such bales, whetheruse e made of one or another de vice or apparatus for that-purpose.
